Tremor and pain hand

Asked for Male, 30 Years

I have been having tremors in my right hand since the age of 13-14. But those were temporary. For last 3-4 month i have been facing pain and weakness with occasional tremors in hand, arm bottom of foot and neck. Apart from that i feel occasional twitching on facial muscles. I have had an MRI recently which was perfectly normal and the Doctor just prescribed me some medicine for anxiety for a month. I Have had high BP for couple of days but that too get controlled. Could you please advise me on what could it be. Thanks!
